Abstract

 In order to study the effect of INTERCROPPING and nitrogen fertilizer treatments on grain and forage yield, afield experiment was conducted at the reaseerch farm of the Islamic Faculty of Shushtar, in 2005. The planting methods laid out in a RSSandomized Complete Block Design (RCBD) in split plots arrangments keeping different nitrogen rates, i e, 50, 100 and 150 Kg/ha as main plots and various fates of INTERCROPPING com - SUNFLOWER as sub plots with tree replications. The INTERCROPPING treatments were SI (%100 SUNFLOWER), S2 (%25 com+%75 SUNFLOWER), S3 (%50 com +%50 SUNFLOWER), S4 (%50 com+ %25 SUNFLOWER), and S5 ((%100 com). The results from the study revealed that the highest and the lowest grain yield in nitrogen fertilizer treatments were observed in 50 and 150 kgN/ha for com. The and in 100 and 50 kgN/ha for SUNFLOWER, respectively.The reduced yield of com plant was attributed to the reduced propotion of com in mixing sistem. Ther was a relationshipamong the reduced yield of the grain and the number of row strips in ear and the number of the kemet in com. The highest and the lowest grain yield were for S5 (%100 SUNFLOWER) and S4 (% 75 com+%25 SUNFLOWER). The oil proportion (in the hybrid levels) increased as a result of decreasing the SUNFLOWER proportion. An increasing in nitrogen proportion raised the LAND EQUIVALENT RATIo (LER). The highest and the lowest LAND EQUIVALENT RATIo for grain yeild were observed in hybrid levels of S4 (%75 com+%25 SUNFLOWER) and S3 (%50 com+%50 SUNFLOWER), respectively.
